LITCHFIELD — An investigation into an armed robbery in Litchfield led to the arrests of seven people in Montgomery County over the weekend.

The trouble started Saturday when three Springfield residents reported that they had been robbed at gunpoint in the 13000 block of Washington Road in Litchfield. They had gone to the address to look at a car for sale, and when they arrived, three armed men allegedly ordered them out of their vehicle. Two of the men fired their weapons into the air on multiple occasions, according to a news release issued Monday by the Montgomery County Sheriff’s Office.

One of the men took $1,000 from one of the victims, and a woman took miscellaneous items, authorities said. The three victims were then allowed to leave.

On Sunday, Montgomery County deputies and Litchfield police officers went to the address on Washington Road and arrested three people: Truman M. Seago, 50, April R. Barnes, 46, and Brittany R. White, 24, all of the Washington Road address.

Sheriff Jim Vazzi said authorities suspect Seago, Barnes and White conspired to commit the robbery. They do not believe they were among the three men and one woman who initially confronted the Springfield trio.

The four people who allegedly did so were arrested later Sunday as authorities simultaneously served three search warrants obtained from information at the Washington Street address.
